作者对103例各种类型的肾盂肾炎患儿和40例健康儿(对照组)于治疗前、治疗后10—12天、临床—实验室缓解期各进行一次HCT试验(硝基蓝四氮唑还原反应),试图借助该试验确定疾病的活动过程、缓解程度和预后。作者的研究发明,肾盂肾炎急性期患儿血液中中性白细胞反应性改变,加强了HCT还原能力。96.1％的病例HCT试验数值升高,显然与疾病的活动性有关,以Ⅱ度活动时最高,相同活动度时患儿HCT试 The authors conducted an HCT test in 103 children with various types of pyelonephritis and 40 healthy children (control group) before treatment, 10-12 days after treatment, and in clinical-laboratory remission (nitroblue tetrazolium Reduction reaction) trying to determine the course of disease activity, degree of remission and prognosis with the help of this experiment. The author’s research found that children with acute pyelonephritis in the blood of neutrophil reactive changes, enhanced HCT reduction. In 96.1% of the cases, the value of HCT test increased obviously in relation to the activity of the disease, with the highest activity in the second degree and the HCT in the same activity
